How to Make a Fruit Fly Trap

The perfect fruit fly trap

Fruit flies are really annoying and seemingly impossible to get rid of. However, it’s very easy to make a fruit fly trap to catch them.

Last week I realized I forgot to put a rubber band around my kombucha in my cupboard. Suddenly I had all these fruit flies in my kitchen.

I saw all kinds of different methods online for catching fruit flies, and most of them seemed confusing to me — and/or messy.

This is so simple — and it really works to catch fruit flies.

How to Make a Fruit Fly Trap

1. Get out a bowl.
2. Put some wine or vinegar in the bowl, with some old fruit (I used red wine and a banana).
3. Put a piece of plastic wrap over the bowl and secure it tightly with a rubber band.
4. Use the tip of a skewer or something long and pointy and poke a bunch of holes in the plastic wrap.
5. Place the bowl in the place in your kitchen where you see most of the fruit flies (and make sure you clean up whatever it was they were attracted to in the first place).

The fruit flies will be attracted to the fruit and wine — and they’ll check in but they won’t check out. I don’t know why, but they can’t fly back through the holes.

  1. What an excellent idea! Did you know, that Kombucha could make a great fruit fly trap too – simply add some Kombucha to a dish, squeeze in a drop of soap and that’s it! Fruit flies fall in and can’t fly out.

  2. That’s exactly what we do to catch them. The kitchen window in our old apartment opened toward the dumpsters, and in the summer we would get the flies, no matter what! They didn’t seem to care we never opened that window… They jumped in anyway. That type of trap worked every time!

  3. This sort of trap works great! I also add just a tiny drop of dishwashing soap to the liquid. This makes the surface of the apple cider vinegar thinner than normal, thus making all the flies fall into the liquid and drown when they try to get a drink.

  4. Awesome! Thanks for the tip! I’ll have to remember this next summer when I’m canning (or we have lots of fruit around). It seems that we have a never-ending supply of fruit flies in the summer… πŸ˜•

  5. Aren’t fruit flies annoying? Whenever we have an outbreak I make a similar trap, but I use a very small glass yogurt jar (with a small amount of apple cider vinegar with a drop of liquid dish dish detergent inside, with an inverted (point side down) paper cone sitting in the jar mouth (the cone tip shouldn’t reach the vinegar level). The fruit flies can go into the jar via the small opening at the tip of the cone, but can’t get out.

  6. @annmarie – the herb guy at my FM (Long Beach Marina – Sunday) gave me a small bouquet of Rue. I put it in a small vase of water…worked like a charm! When they get out of control, I grab another bouquet. I noticed that some nurseries have Rue potted as well. Love the wine idea. They probably don’t fly out because they got wasted πŸ™‚

  7. The fact that they can’t find the way back through the holes is proof that fruit flies aren’t the brightest crayon in the box! This is a great idea and I use the same method successfully, but I use a paper or plastic disposable cup so that when it starts getting too old and most of the flies have found their way in, I can just toss it in the trash.

  8. I have 4 traps set up using various methods and we still have a huge fruit fly problem. I have one with kombucha, one with ACV and dish soap, another with honey and yeast (they seemed to like this one best) and I forget the other one, all with either the punctured saran wrap or an inverted cone over top. I have discovered they all work equally well and still we have a fruit fly problem, even though it’s deep winter here, grrr. The other day I discovered a hidden rotten carrot where they appeared to be spawning and cleaning that up seems to helped somewhat but I know they’re breeding somewhere else now.

  9. Oh my gosh–I HATE fruitflies! I almost want to scream WHERE DO THEY COME FROM!!! it seems the more we have natural ferments, the more the little suckers want to hang around my kitchen. I’ve never intentionally used wine before, but did discover what a convenient trap it was when a houseguest left a glass in the dining room (we rarely use it, but the ferments are only about 5 feet on the other side of the wall) and I didn’t discover it for a few days… They didn’t even want any fruit! Of course, it was a sweet wine to begin with, and even without a cover–or soap to reduce surface tension–they ended up in the drink! Still, I think capturing them with the saran wrap is a much better way to go. Thanks for the post!

  10. I hate those fruit flies too, especially since they don’t just like fruit. They like my daughter’s guinea pig. The fastest and dare I say most fun to rid the kitchen of the little buggers is to vacuum them up using the narrow extension. You can almost heart their little holler’s as they flap their little wings, “Nooooooooo.” Look up, they like to hide on the ceiling.

  11. @Hannah, excellent idea. I’m going to try that as I’ve got some fresh kombucha just brewed. My flies, and I’m not sure they’re fruit flies, hang out around my spider plants. They may be a different species, but your trick should do it. I’ll give it a try

  12. We use that method, too. One day I discovered that we were out of plastic wrap, so we left it off and added a touch of dishwashing liquid and water to the wine to reduce the tension on the surface. It worked fine — but in our ever cluttered kitchen, we did have to be more careful not to knock it over.

  13. I do this to, only without the saran wrap…. but now that I see how it works with that it seems foolish for me to not to, so I’ll give that a try πŸ™‚

    I found that brandy works really well to attract flies, better than just wine or the ACV stuff or the murphys soap in water.. of course, I don’t recommend wasting brandy or wine, but since I’m a sipper with pretty much anything I drink, there’s usually something left in the bottom of the glass that I can use as bait when it’s fly season.

  14. Oh my gosh, that’s so funny. My husband used to make wine with his family. The fermenting process definitely brings those little suckers. What a great idea, thanks Ann Marie.
    Off topic, does anyone know of a recipe for making cornbread with MASA flour? I only have recipes for treating the cornmeal with lime first. Using masa flour changes the recipe to much, and I wasn’t sure how to adapt it. Thanks all!

  15. TODAY I am trying this. I have actually had some come to my home, love the kombucha, but opt not to make it themselves, (even though I offered them all supplies!), because they saw how the fruit flies liked to hover around it. That’s about to change! πŸ™‚

  16. I think the reason for them finding their way in is the smell of the vinegar. Finding their way out isn’t possible because there’s no vinegar on the outside. This is the only logical explanation I could come up with.
